Honestly, I don't do anything directly to support them. I think my loved ones just me to be happy and healthy, and by taking care of myself I'm doing just that. But I do try to "Pay it Forward", and support others with D (both online and in real life).
When I decided, at the last minute, to participate in the JDRF Walk-for-a-Cure in the fall, I sent out an emotional plea for sponsorships to my close family. The e-mail response I got from my father was quite touching, and was, in a sense, a reassurance that in our family we all help each other.
He wrote, in part (I won't copy the whole message) a message that brings a tear to my eye every time I read it:
"Mom and I are proud to sponsor you ... We're also extremely proud of you. You have lived with diabetes now for about 30 years. We watched you having to make adjustments in your life at a very young age. We know it hasn't always been easy, but you handled it with such maturity and with an obvious sense of self responsibility. Your act ... just reinforces to us what we already know about you. You are a compassionate and caring person with a good heart and a soft spot for those who could use some help. We could not have asked for a more wonderful son..."
As a parent myself, I believe that the best way to express gratitude and support to those who raised you is to adopt and embrace the values they worked so hard to teach. Every parent relishes the opportunity for their kids to make them proud, and I think I've done that.
